Because lava is in the center and lavas hot
Answer:
13 u2 = 0 – (2 × –2 m/s2 × 6 m) = 24, u = 4.9 m
Explanation:
Answer:
c. It refers to any government program that tends to reduce fluctuations in GDP automatically.
Explanation:
Automatic Stabilizer is nothing but any scheme or program that that tends to reduce fluctuations in GDP automatically. It is generally intended to stabilize the GDP of a nation.
For examples In cases of economic slow down, the government sells its ownership in public sectors undertakings like, railways, oil and natural gases, to private players. So, that government has some money to combat the slowdown.
Answer:
Because the light reflects multiple times until it gets to the Cassegrain focus.
Explanation:
The Cassegrain design can be seen in a reflecting telescope. In this type of design the light is collected by a concave mirror, and then intercepted by a secondary convex mirror, and sends it down to a central opening in the primary mirror (concave mirror), in which a detector is placed (Cassegrain focus)
Since, the light is reflected many times due to Cassegrain design, that leads to shorter telescopes.
Answer:
a) the acceleration is -9.8 m/s^2 (gravity's acceleration), the magnitude is 9.8 m/s^2 and the direction is downwards.
The pebble is not decelerating since the magnitude of it's speed is increasing, even if it is on a negative direction.
b) after 0.5 s the pebble is 5.725 meters down. (or -5.725m from it's initial position.)
Explanation:
a) the acceleration is given only by gravity, it's the only force acting on the pebble, the slingshot only gives the pebble an initial speed.
b) To calculate the position we use the equation
y0 + v0·t + ½·g·t² = yf
replacing:
0 + (-9.0m/s) * 0.5s + 1/2 (-9.8)*0.5² = yf
-5.725 = yf
